UPANISHADS.
it impossible to come to a decision on this point. Even so early as the hymns of the Rig-veda we meet with these numbers assigned to days and months and seasons, rivers and countries, sacrifices and deities. They clearly prove the existence of a considerable amount of intellectual labour which had become fixed and traditional before the composition of certain hymns, and they prove the same in the case of certain Upanishads. But beyond this, for the present, I should not like to go; and I must say that the attempts of most of the Indian commentators at explaining such numbers by a reference to later systems of philosophy or cosmology, are generally very forced and unsatisfactory.
One more point I ought to mention as indicating the age of the Svetâsvatara-upanishad, and that is the obscurity of many of its verses, which may be due to a corruption of the text, and the number of various readings, recognised as such, by the commentators. Some of them have been mentioned in the notes to my translation.
The text of this Upanishad was printed by Dr. Roer in the Bibliotheca Indica, with Sankara's commentary. I have consulted besides, the commentary of Vigñânâtman, the pupil of Paramahamsa-parivrâgakâkârya-srîmag-Gñanottamâkârya, MS. I. O. 1133 ; and a third commentary, by Sankarananda, the pupil of Paramahamsa-parivrâgakâkâryânandâtman, MS. I. O. 1878. These were kindly lent me by Dr. Rost, the learned and liberal librarian of the India Office.
VI. PRASÑA-UPANISHAD. This Upanishad is called the Prasña or Shat-prasñaupanishad, and at the end of a chapter we find occasionally iti prasñaprativakanam, i.e. thus ends the answer to the question. It is ascribed to the Atharva-veda, and occasionally to the Pippalâda-sâkhâ, one of the most important sâkhâs of that Veda. Pippalada is mentioned in the Upanishad as the name of the principal teacher. .
Sankara, in the beginning of his commentary, says:
